Merge branch 'for-linus' of git://git.o-hand.com/linux-rpurdie-backlight

* 'for-linus' of git://git.o-hand.com/linux-rpurdie-backlight:
  backlight: Rename the corgi backlight driver to generic
  backlight: add support for Toppoly TDO35S series to tdo24m lcd driver
  backlight: Add suspend/resume support to the backlight core
  bd->props.brightness doesn't reflect the actual backlight level.
  backlight: Support VGA/QVGA mode switching in tosa_lcd
  backlight: Catch invalid input in sysfs attributes
  backlight: Value of ILI9320_RGB_IF2 register should not be hardcoded
  backlight: crbllcd_bl - Use platform_device_register_simple()
  backlight: progear_bl - Use platform_device_register_simple()
  backlight: hp680_bl - Use platform_device_register_simple()
